BUTTER-PRIllTT MACHINE.

Specification of Letters Patent.

Application filed September 2, 1920. Serial No. 407,644.

To all wiwm it may concern:

Be it known that we, HENRY H. DOERING and CHARLES DOERING, citizens; of 'the United States, and residents of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Butter-Print Machines, of which the following is a description, reference be ing had to the accompanying drawings, which form a part of our specification.

Our invention relatesto a power operated butter print or molding machine which will be self-feeding; wherein the butter or butter substitute willnot be subjected to a too great pressure at the initial charging end; with the receiving end of the chamber or receptacle portion of the machine bein such that pressure on the material will e retarded and operation of the machine made automatic; while the size of the prints may be controlled and varied through simple, ad-

justable mechanism.

One object of our invention is to provide means whereby the material will not only be fed or conveyed from the receiving to the discharging end of the machine, but which means is of such formation and so related to the interior of the receptacle, that a faster and more uniform action is ob tained; said means in conjunction with improved molsture dlstributlng means, which enables a larger percentage of moisture to be ducin an improved product havin a smoot er gram and more uniform b end than has heretofore been provided.

' saving of time and labor, while also providin a more sanitary product.

The purposes and advantages of our improved machine will be more readily comprehended from the following detailed description of the drawings, wherein:

Figure 1 is a side elevation of our improved machine.

provided in the product or butter, pro-' Fig. 2 is a top plan view thereof.

Fig. 3 is a longitudinal sectional view taken on the line 33 of Fig. 2, looking in the direction of the arrows.

Fig. 4 is a vertical sectional view taken on the line 4-4 of Fig. 1, looking in the direction of the arrows.

Fig. 5 is a detail view, in elevation, of the moisture controlling means.

The construction illustrated in the drawingsas an embodiment of our invention, we believe to be the simplest and best form, but the invention may havq expression in somewhat different mechanical form with out departing from the spirit of the invention.

The machine as illustrated comprises a suitable supporting structure as shown at 10, preferably of angle members; with one end of the table or supporting structure provided with a bracket 11, on which a' portion of an electric motor 12 is mounted. The motor-shaft is provided with a gear 13 which meshes with a large gear 14, rotatably mounted at the end of the table or supporting frame of the machine. The shaft on which gear 14 is secured is also provided with a small gear 15, which meshes with a gear 16 secured to the end of a shaft which is provided with a clutch 17. Clutch 17 is adapted to be controlled from the discharging end of the machine by means of a foot lever 18 connected to a bell-crank lever 19, secured to the supporting frame of the machine; the clutch being normally out of clutching position through the action of a sprin 20 secured to the end of a lever 21,

to whlch one end of link or rod 22 is also sestruct the worms or screws 25 and 26, as well as the receptacle portion of the machine, of wood and for that reason the receptacle portion comprises a plurality of blocks 27 and 28 secured together in any suitable manner. These blocks are provided with a pair of substantially semi-cylindrical grooves; thegrooves of one block registering with those of the other; the grooves forming channels of dimensions just sufficient to accommodate the worms .orscrews and permit free rotation thereof; while the grooves or channels, which are disposed parallel with each other and in the same horizontal plane, are arranged in commun cation with each other by means of a long;- tudinal groove disposed substantially in the same plane as the longitudinal axes of the worms, as shown at 29, in Fig. 4.

-The worms 25 and 26 are alike in construction, being both formed with a special shown and described results in a more uniform and fast feed of the product introduced through the hopper 32. It has been found in practice, that uniformity and positiveness of feed in machines of the character -to which-our invention relates, depends to a considerable extent on the formation of the hopper end of the worm or screw channels and for that reason the upper member or block 27 adjacent the hopper 32 is cut away at an inclination so as to provide the considerably flared orifice as at 33 for the grooves, With this formation of the inlet or feeding end, pressure on the butter or butter substitute is retarded and the rolls or worms are enabled to rapidly take up the butter and cause it to be fed through the machine in a uniform manner, thereby insuring a consistency in the ltexture and weight of the prints of butter provided by the machine.

The worms 25, 26, terminate at the ends of the blocks or members 27 and 28, where the machine is provided with a moisture distributing element which also induces a proper blending of the product. The element is preferably inthe natureof a metal plate 34, of predetermined thickness and provided with a plurality of similar perforations of predetermined diameter and equi-distances apart as shown at 35 in Fig.

the perforations being disposed throughout that portion of the plate which reg- V isters with the open ends of the grooves or printing is entirely channels in which the worms 25 and 26 are located, see Fig. 3. The plate 34 is shown provided with bolt-holes at 36 in the marginal portion, which enable the plate to be securely bolted to members 27, 28 by bolts which "also secure the molding head 37 to the delivery end of the members.

Our improved plate 34 causes the butter or butter substitute to be forced into the molding'head 37 in vermicular form; the

various particles being subsequently brought together i into more or less compact form through the action of the regulable molding head 37.

By employing the 'fo raminated plate or member 34, the desired amount of moisture can be provided in the finished product, as

the moisture adhering to the pencil like porv tions and that passing through the plate, will be pocketed as .it were between the numerous vermicular portions of butter improved rolls or worms. and channel or groove construction, results in a better v blending of the butter andprovides a product of finer and smoother grain or texture possessing the desired amount of moisturecontent.

As a result of our improved machine, the

use of a separate blending machine is obviated and the necessity of handling the butter or butter substitute for blending and eliminated. With our improved machine, ing of the butter is accomplished by a single machine and operation, thereby saving conthe blending and printsiderable time and expense and at the same I time obviating the necessity of manual 7 manipulation by operators having salt sores; the use of our improved machine therefore resulting in a more sanitaryprodnot than has heretofore been'the case,

The size and width of the butter discharging from the molding head may be regulated by regulable throat-members which may be arranged and operable substantially similar to those shown and described in the pending I application of one of the applicants and bearing Serial #293,712; the machine being capable of producing varying'sized prints.

Our machine with its improved construction of feeding end and special construction of worms, produces a positive self-feeding 'machine which overcomes the difliculties heretofore encountered in obtaining uniformity of feed because of the resistance offered at the introducing or feeding end of machines as. heretofore constructed; while at the same time both labor and expense are saved and a more uniform product possess-- 1 substitute is discharged from the throat of shown in Fig. 1, at which point the butter isthe molding head onto a series of freely rotating rollers shown at 38, mounted as cut into the desired prints and then discharged onto an' endless belt 39; the endless belt being driven from a pulley 40 mounted on a trunnion to which bevel gear 41 is se-l scribed, a main body portion provided with cured, which meshes with a bevel gear 42 secured to the end of a shaft 43 driven by means of a gear 44 which meshes with the gear 16; the construction causing a positive and proper driving of the endless element 39, commensurate with the speed of operation of the remainder of the machine.

In addition to providin wooden worms or screws of the particu ar construction shown. and described, the worms are not only arranged to Operate in unisonv at the same speed and in opposite directions, but the spirals of one worm are preferably arranged in staggered relation with the spirals of the other worm as shown in Fig. 2, thus greatly assisting in the proper operation and positive feeding of the butter along the grooves of the main portion of the machine and thence through the foraminated member or plate 34. It will be understood of course, that the plate 34 is preferably of substantial thickness to induce pro er action in separating the butter into t e vermicular portions described and also permit moisture to pass through to the moldin head side of the plate, where it is entrained with or caused to adhere to the various butter portions and thereby enveloped or incased when said ortions are brought into compact form by t e molding head.

What we claim and 'wish to secure by Letters Patent is:

1. In a machine of the character dethe grooves or spaces intermediate of the s irals of said worms being deeper adjacent t e forward sides of the spirals than at the rear sides thereof.

2. machine of the character described, comprising a main body portion provided with a pair of cylindrical grooves disposed parallel and in .communication with each other throughout the. lengths thereof, a
